public class Magnifier extends SoTranslate2Dragger
(Preview Feature) Shape node to display a magnified view of a region of the screen.

Preview Feature means this class is fully supported and can be used in Open Inventor applications. Being tagged as a Preview Feature just means that the implementation is still subject to API changes and adjustments based on feedback from early adopters. Please be also aware that source compatibility might be broken regardless of the Open Inventor compatibility changes policy due to our commitment to bring needed changes to be sure the specifications of this Preview Feature match the expectations of our customers.

This node displays a circular magnified (zoomed in) view of the screen region under the center of the circle. The magnifier is an SoTranslate2Dragger so the user can click and drag to move it around the screen.

Limitations:

  • Can only be used in a "2D" viewing environment using an SoOrthographicCamera.
    For example viewing a single slice of a medical volume.

  • Can only be used with the default camera orientation (looking toward -Z).
